Answer:
The octet rule is a chemical rule of thumb that reflects the observation that main group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas
Explanation:
When liquid is poured into a container, although its shape is altered, the overall volume remains the same. Therefore, the answer is that the volume of a liquid does not change when it is poured into a new container.
The reason as for why there are decimal values for atomic mass values, is because, it is the average of all of the possible atomic masses that can be formed and or present, by taking varying number of neutrons. This varying number of neutrons causes different mass values to be present and by taking the average of the atomic masses, from all possible isotopes, the value yields an average or approximate atomic mass based on all of the atomic masses formed from their unique number of neutrons.
Electrons are not included as they are not found within the nucleus of the atom, for which the atomic mass value can be obtained. They are found outside the Nucleus, within orbitals, of regions of space.
Answer: a. The elements iron in the nail and oxygen from the air combine to form the compound rust.
Iron, Fe: is an element
Oxygen, O: is an element
Rust, Fe3O4: this formula identifies the product as a compound
